Question

An interior angle of a triangle is of measure 1400. If the corresponding interior opposite angles are in the ratio 3 : 4. Find the measure of all the angles of the triangle.​

Answer 1

Answer:

The angles are 16.8 22.4 and 140°

Step-by-step explanation:

Let the corresponding interior angles are 3x and 4x .

Acc to the formula

3x + 4x + 140 = 180

7x + 140 = 180

7x = 180- 140 = 40

x = 40/7 = 5.6

The angles are 3×5.6 = 16.8

4 × 5.6 =22.4
